BOOTH BENTLEY, or cLAYToN-LE-woons, NEAR. CHOR- SHUTTLE-CHECKING MECHANISM non Looms,

Application 'na' May '2,

To all whom it may concern:

Be it known that we, JOSHUA ARTHUR BAPBER LOMAX, WILLIAM TURNER, JOHN TuRNER, and'JAMEs BOOTH BENTLEY, subjects of the King of Great Britain, and residents, respectively, ofRavenhurst, ,Heaton, Bolton, in the county of Lancaster, England, 19 Mayfield Road, Chorl'e'y, in the same county, 14 Friday Street, 'Chorley, aforesaid, and Brownley Terrace, Clayton-le- Woods, near Charley, aforesaid, have invented, a certain new and useful Improvement in Shuttle-Checking Mechanism for Looms, of whichtlie following description, having reference to the accompanying sheets of drawings, is a specification.

It relates to means for checking shuttles when they arrive the shuttleboxes in looms whether same are of the fast reed or of the loose reed type, and our said invention consists the employment of devices which will efficiently attain the object desired and will also so guide and conduct the shuttle throughout its operations that the same is caused to come in contact with the picker at all times by striking the said picker at one and the same place, thus a great saving in pickers is effected on account of avoiding the indentation of a large space on the picker by the tip of the shuttle as is well understood. The precision with which the shuttle arrives at the same place within the shuttle box is such that new pickers may be mounted in position upon their picker spin- 35 dies and the loom started into action without necessitating the preparation or adjustment of said pickers to meet any actions of the tips of the shuttles from commencing with a new picker t0 the complete wearing out of the samepicker, since said tips of the shuttle at all times strike or come into contact with the same point or part of the picker with the results stated.

In the accompanying sheet of drawings illustrative of our invention,

Fig. 1 is a front elevation of sufficient of the end of a slayboard or lay to show the well known manner, but said spring 1922. Serial No. 55332253.

application thereto of our improved devices. I Figi. 2 is a plan'ofthe parts shown by Fig. 3 is a view of the parts shown by Figs. 1 and 2 as seen from behind. Fig.4 is a sectional end elevation showing the application of our improved devices as is hereinafter explained. I 1 Figs. 5 and 6 are perspective views of parts hereinafter more particularly described. B indicates the slayboard or lay of the loom, C the hand rail and D the lay-sword. In carrying our invention into eifect we makeuse of a swell lever or swell device 2 at the front. of the shuttle box 3 as well as a swell device (which is in the form of a :65

swell lever) 4; at the rear of saidshuttle box 3 on the slayboard B. The swell device 2 at the front of the'shuttle box is situated at theentrance thereto as shown by Figs. 1 and 2 where it is operated or held in position by the tension of a spring 5 so that the incoming shuttle 6 will firstly come in contact with said device 2 in order that the actions of this swell device 2 may force the shuttle 6 against the straight surface of the back a of the shuttle box 3 by which means its path is secured in a direct or straight line until it moves forward within the shuttle box 3 to come into contact with" the second swell lever 4 which is situated at the back of the shuttle box 3 as shown by Figs. 2 and 3. Said swell 4L isioperated by the sprin 7 in will permit the movement of the swell 4 by the actions of a less force than is required to move the swell 2.

By this arrangement of shuttle swells 2 and 4 the shuttle 6 is guided in the first part of its path within the shuttle box 3 by the front swell 2 and on reaching the swell 4 in the rear wall thereof any deflection that takes place has the effect of forcin the other end 2') of the shuttle 6 more rmly against the back wall a of the shuttle box 3 by which arrangement we have found that the shuttle 6 at all times strikes the picker 8 in one and the same place throughout all of the useful period of working of said picker 8.

In making use of the devices 2 and 4 as described we have also found that on the shuttleG being picked or thrown out of the shuttle-ibox the gguiding actress of; the swell 4 at the back of the shuttle box in conjunction with the guiding actions of the swell; 2 atthefront have the. effect of; causing theleading end-rbi ofithe-cshuttlertoi be directed towards the reed 10 and therefore said shuttle 6 is kept in its desired path with very little likelihood ofbeing thrown out of same thus ensuring the arrival of the shuttle 6 in the shuttlebox 'at the other end of; the. loops with, great, regularity as o s e a t pos t on: er in;

The fornrof swell 2 which we prefer to make use of is of, the grooved character shown by Eigsifi and-5, While the front wall (Z of the shuttle box3 is cut away to receive the partsy, andylfof 'this swell .2 above and below the central part 72. ofvsaid wall which remains intact. v g

This arran ement-enables,the swell; 2 to sli'le within the guiding surfaces is, (see Fig.- 6 adjoiningthe part 71, and at the same time affords space between the inner surquently only a very short check strap 11 mounted upon the picker spindle 12 for the picker 8 to contact with, is required andfthis check strap 11 is arranged to take over said picker spindle. 12 and extend towards the back of.- the shuttlebox 3 where we mount a spring 13 to keep it normally in its forward position to act as a slight buffer for the picker when it is propelled by the incoming shuttle 6,-to its rearmost position .as shown by Figs. 1 and 2.

-The spring 5 which actuates the front swell may be. usedin conjunction with a sliding swell 2 as shown in the drawings and which we. preferably make use of, but

we may also make useof a hinged swell at the front of the shuttle box similar in charactor to the hinged swell 4 which we use at the. back of the shuttle box.

Further than this the swell lever 4 may be of the character shown so that it may be used for actuating the stop rod of a loom when our devices are used in connection with what is known as a fast reed loom, while the other arrangements shown may be used in conjunction with what are known as a loose reed loom.

Such being the nature and object of our said invention what we claim is shuttlechecking; mechanism for looms, a shuttle box, a swell mounted upon the front wall of the shuttle box near the entrance thereto, a. spring for acting upon =sa1d'- swell, another swell mountedonthe rear wall of the shuttle box, andrfurtherxfrom the entrance to the box than said first mentioned-swelh-anda spring for actuating said rear swell, the portion of said box opposed to said'lastmentioned swell being substantially stationary to maintain a fixed home for the. end of the shuttle, approaching the outer'end" of the'box a shuttle checking mechanism for. looms, a shuttle, box, a swell reciprocably mounted upon the front wall of the shuttle bOX IlggtI, the entrance thereto, aspring for acting upon said swell, another swell mounted, on the rear wallfofthe shuttle box, and further from; the entrance than said first mentionedgs well, and a spring for actuating said rear swell, the portion of said box opposed to said lastmentioned swell being substantially stationary to maintain a fixed home "for the end of the shuttle approaching the outer end; of thebox.

3, In shuttle checking mechanism for looms, a shuttle box having openings extending through its front wall near the entrance thereto, a swellhaving spaced lugs extending through said openings, said swell spanning the portion of the front wall between said openings, and the lugs thereof having inclined surfaces for contact with the shuttle, there being aspace between said surfaces, a spring for actuating said swell, another swell mounted in the rear wall of the box further from the entrance than said first mentioned swell, and spring means for actuating-said last mentioned swell.

4. In, shuttle checking mechanism for looms, a shuttle box having openings extending through its front wall near the entrance thereto, a reciprocable swell having spaced lugs, extending through said openings, said swell spanning the portion of the front wall between said openings, and the lugs thereof having inclined surfaces for contact with the shuttle, there being a space between said surface, a spring for actuating said swell, another swell mounted in the rear wall of the box further from the entrance, and spring means for actuating said last mentioned swell.

5. In shuttle checking mechanism for looms, a shuttle box, having spaced openings formed in its front wall, a swell positioned adjacent the entrance to said box, and having spaced means extending through openings in the front wall of the box, inclined surfaces on said means adapted to engage a shuttle, there being a space between said surfaces, a swell further within said box and extending through the rear wall thereof, the portion of said box opposite said last men tioned swell being substantially stationary to maintain a fixed home for the end of the shuttle approaching the outer end of the 10 shuttle box, and spring means for actuating said swells.
